c语言基于链式存储结构的校运会径赛管理程序设计 利用链式存储结构，为校运会 100 米初赛，编写一个管理程序，记录每个选手的姓名、编号、组号和成绩，并通过数字化菜单为用户提供数据录入、抽签、查找和输出晋级名单的功能。

以下是一个简单的 C 语言示例程序，展示了如何实现基于链式存储结构的校运会径赛管理程序的基本框架： ```c #include <stdio.h> #include <stdlib.h> #include <string.h> // 定义选手结构体 typedef struct Athlete { char name[50]; int number; int groupNumber; float score; struct Athlete *next; } Athlete; // 新建选手节点 Athlete* createAthlete(char name[], int number, int groupNumber, float score) { Athlete *newAthlete = (Athlete*)malloc(sizeof(Athlete)); strcpy(newAthlete->name, name); newAthlete->number = number; newAthlete->groupNumber = groupNumber; newAthlete->score = score; newAthlete->next = NULL; return newAthlete; } // 插入选手节点 void insertAthlete(Athlete head, char name[], int number, int groupNumber, float score) { Athlete *newAthlete = createAthlete(name, number, groupNumber, score); if (*head == NULL) { *head = newAthlete; } else { Athlete *current = *head; while (current->next!= NULL) { current = current->next; } current->next = newAthlete; } } // 打印链表 void printList(Athlete *head) { Athlete *current = head; while (current!= NULL) { printf("Name: %s, Number: %d, Group Number: %d, Score: %.2f\n", current->name, current->number, current->groupNumber, current->score); current = current->next; } } // 查找选手 Athlete* findAthlete(Athlete *head, int number) { Athlete *current = head; while (current!= NULL) { if (current->number == number) { return current; } current = current->next; } return NULL; } // 释放链表内存 void freeList(Athlete *head) { Athlete *current = head; Athlete *temp; while (current!= NULL) { temp = current; current = current->next; free(temp); } } int main() { Athlete *head = NULL; // 数据录入 insertAthlete(&head, "张三", 1, 1, 12.5); insertAthlete(&head, "李四", 2, 1, 13.0); insertAthlete(&head, "王五", 3, 2, 12.8); // 打印链表 printf("All Athletes:\n"); printList(head); // 查找选手 Athlete *found = findAthlete(head, 2); if (found!= NULL) { printf("Found Athlete: Name: %s, Number: %d, Group Number: %d, Score: %.2f\n", found->name, found->number, found->groupNumber, found->score); } else { printf("Athlete not found\n"); } // 释放链表内存 freeList(head); return 0; } ``` 以下是三个改进建议： 1. 增加错误处理机制，例如在内存分配失败或文件操作出错时进行相应的处理。 2. 优化查找算法，使用更高效的查找方法，如二分查找。 3. 对输入数据进行有效性验证，确保用户输入的信息符合预期格式和范围。 [2024-12-28 13:00:35 | AI写代码神器 | 892点数解答]
